Mark Text for an Index
Creating an Index is similar to creating a Table of
Contents.
Try This: Mark Text for the Index
Select the text your would like to include in the
Index.
Go to
Reference -> Index.
Select:
Mark Entry.

What Do You See? The
text you selected will be the Main entry. You can add a
Subentry or Cross-reference if you wish. When you Mark
an entry, the Show/Hide will reveal the Index code: {XE "Sample
Text"}.
Repeat these steps for each topic that you want to
include in the Index.
